What sort of succession follows when a farmland is abandoned and allowed to grow without human inference (primary or secondary)? explain your answer.

Secondary succession because it is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat.

Explanation:

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

currents is the correct answer.
